RAILWAY-SIGNAL.

SPECIFICATION forming part of Letters Patent N o. 394,466, dated December 11, 1888. Application filed May 24, 1888. Serial No. 274,916. (No model.)

T0 all whont it may concern:

Be it known that I, NORMAN T. DE GoLYER, of VVaupun, in the county of Dodge, and in the State of Vvisconsin, have invented certain new and useful Improvements in Railway- Signals; and I do hereby declare that the following is a full, clear, and exact description thereof. y

My invention relates to railway-signals; and it consists in certain peculiarities of construction and combination of parts, to be hereinafter described with reference to the accompanying drawings, and subsequently claimed.

In the drawings, Figure l represents a vertical transverse section of a Caboose-car having my invention applied thereto, the section being taken on line l l, Fig. 2; Fig. 2, a vertical longitudinal section of the same taken on line 2 2, Fig. l; Fig. 3, a horizontal section taken on line 3 3, Fig. 4; Fig. 4, a vertical section taken on line 4 4, Fig. 3, and illustrating a mechanism for partially rotating a lantern that forms part of my signal; Fig. 5, a horizontal section taken on line 5 5, Fig. 6; Fig. 6, avertical section taken on line (i (i, Fig. 5,and illustrating the construction of a lantern-support employed in my signal; Fig. 7, a plan view, partly in section, of a sprocket-gear mechanism that forms part of my invention; and Fig. 8 a section taken on line 8 8, Fig. 2.

Referring by letter to the drawings, A represents an ordinary Caboose-car. A vertical shaft, B, has its bearings in a bracket, C, attached to one of the car-sills, and in another bracket, D, secured lto an inner side of said car near its top. To the lower end of the shaft B, I attach a bevel gear-wheel, b, that meshes with a similar wheel, c, on a horizontal shaft, E, that has its bearings in brackets (l depending from sills of the car. Fast on the shaft E is a sprocket-wheel, F, and loosely connected to said shaft, so as to be pivotally adjustable thereon, are arms G, the outer ends of these arms being provided with bearings e for trunnions f on another sprocketwheel, H, over which and the one F is arranged a drive-chain, I, designed to be brought in and out of engagement with a sprocketwheel, J, on an axle, K, of the car, accordingly as the arms G are raised or lowered, the aXle being provided with guards K', that prevent lateral displacement of said chain.

In order that the arms G may be readily raised or lowered, I provide each of the bearings e with an eye, g, to which I attach a yoke, h, that connects with a pivoted lever, L', that has a rod-connection, j, with another lever, L, pivoted to a bracket, L', on the floor of the car, the latter lever being held in its adjusted position by means of a pin, lc, passed through it and one of a series of perforations in said bracket.

Fast on the upper end of the shaft B is a bevel gear-wheel, M,that meshes with a similar wheel, N, on a shaft, O, that has its bearings on the bracket D, as illustrated in Fig. l. fristed to a disk, P, on the shaft O is a vertical rod, Q, that connects with a bellcrank, R, that is pivotally connected to the inner side of the turret A' of the car and has a horizontal rod-connection with auotherbellcrank, R', pivotally connected to the turret on the opposite side of the car. Both bellcranks have a link-connectiomn, with crankarms p on shafts S, that have their bearings q on the top of the turret A', as best illustrated in Fig. 2. Fast on the shafts S are arms T, that carry shields l", arranged to come in front and rear of signal-lanterns U U', arranged above the turret on opposite sides of the latter. y

The lantern U is fixed on a base, Y, that is fast on a vertical shaft, V', that has its bearings in brackets r, projecting from the adjacent inner side of the car, and fast on this shaft is an arm, s, that is connected by a link, t, with a plate, NV, that is slipped onto the shaft B, to rest upon a collar, W', fast thereon.

The plate \V is held in frictional contact with the collar W' by means of a spiral spring, X, that surrounds the shaft B, between said plate and the bracket D, the latter being provided with depending fingers i z", as best illustrated by Fig. 4.

In the operation of my invention, when the car is moving forward and the drive-chain I is in gear with the sprocket-wheel J, motion is communicated from the axle K, through bevel-geared shafts E B O, to the rod Q, and thus the bell-cranks R R' ar-e actuated to IOO oscillate the shafts S, thereby causing the shields T on the arms T to alternately show and conceal the front and rear bulls-eyes of the lanterns U U', said arms being so arranged on their respective shafts that when the car is at a standstill the light of only one lantern will be discernible, as illustrated in Fig. l.

In practice when the car .is moving forward the lantern U shows a red light and the lantern U a white light, the link t, connecting the arm s on the shaft V, being in contact with the iinger e', depending from the bracket D, and when the light of Vone lantern is eX- posed the light of the other will be concealed. Now, should the car be moved in an opposite direction, the rotation of shaft B will be reversed, and consequently the frictional contact of the collar XV and plate WV will cause the shaft V to revolve, and thereby give the lantern U a quarter-turn to bring the red bulls-eyes of said lantern in line with the movement of said car, the revolution of the latter shaft being limited by the finger fu, depending from the bracketD.

By the operation just described it will be seen that when the car is moving backward each of the two red lights will be alternately shown and concealed by the-movement of the shields 'I" "When the car again starts on its forward movement, a reverse operation to that just described takes place, and the opposite red and white lights are again in line with the movement of said car.

During the day, or at such other times when it may not be desirable to operate the signal, the lever L is actuated to raise the arms G, and thereby bring the drive-chain I out of gear with the sprocket-wheel J on the caraXle K. 4 A

Vhile I have shown an d described a sprocket-gear for communicating motion from the car-axle K, it is obvious that a friction or other form of gear may be used for the same purpose, andI do not wish to be understood as limiting myself to any particular style of gear by which the revolution of said shaft is accomplished, although that shown will probably be the one preferred.

By the above description it will be seen that I provide a signal that will readily show, whether the car is moving or standing still, and which in the former case Will indicate the direction of the movement.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. The combination, with a railway-car, of a signal comprising two lanterns, one of which is pivoted, crank-shafts arranged adjacent to the lanterns, a shield or shields connected to the crank-shafts, a shaft and gear mechanism, substantially as described, for oscillating lsaid shafts, whereby the light of the lanterns is alternately shown and, concealed, and a linkconnection, substantially as described, for uniting the pivoted lan tern with said shaft and gear mechanism, whereby a partial revolution is imparted to said pivoted lantern when the car starts on its backward movement, as and forthe purpose set forth.

2. A railwaysign al comprising two oppositely-arran ged lanterns having front and rear bulls-eyes, crank-shafts arranged adjacent to the lanterns, arms connected to the shafts to come in front and rear of said lanterns, shields carried by the arms, and means, substantially as described, for rocking said shafts, as an d for the purpose set forth.

3. The combination of a railway-car, a lantern arranged thereon, a crank shaft arranged adjacent to the lantern, a shield or shields connected to the crank-shaft, a bevelgear mechanism connected to said crankshaft, a sprocketwheel fast on an axle of the car, a drive-chain for engagement with the sprocket-wheel, and other sprocket-wheels connected to said bevel-gear mechanism and arranged to support said drive-chain, substantially as and for the purpose set forth.

4. The combination of a railway-car, a lantern arranged thereon, a crank shaft arranged adjacent to the lantern, a shield or shields connected to the crank-shaft, a bevelgear mechanism connected to said crankshaft, a sprocket-wheel fast on an axle of the car, a sprocket-Wheel connected to said bevelgear mechanism, arms pivotally connected to said gear, another sprocket-wheeltrunnioned in the pivotal arms, a drive-chain carried by the last two sprocket-wheels, and a lever mechanism for actuating said arms, whereby the drive-chain s brought in and out of engagement with said sprocket-wheel on the car-axle, substantially as set forth.

5. The combination of arailway-car, the 1antern U', arranged outside-the car, the vertical shaft V connected to the lantern, the shaft B, having a link-connection with the one V', and means, substantially as described, for actuating the latter shaft, as and for the purpose set forth.

6. The combination of a railway-car, the lantern U, arranged outside the car, the vertical vshaft V, connected to the lantern, the shaft B, provided with the collar IV', the loose plate IN, supported by said collar, the spring X, ara ranged on the shaft B to exert its force against said plate, the arm s and link. t, connecting shaft V andv plate iV, the bracket D, secured to the side of the car and provided with iingers c fu', arranged'to straddle said link, and means,.sulostantially as described, for actuating said shaft B, as and for the purpose set forth. A

7. A railway-signal comprising a pivoted lantern provided with two lights of different colors and arranged to normally show but one color of light, a shield for alternately revealing and concealing the light, a shaft and gear mechanism, substantially as described, for
